SetDlgGradient

[oliveiros junior]

Hey guys,

I would like to know if the gradient generated by the setdlggrandient function can be horizontal?

regards

[nageswaragunupudi]

Try like this:

Code: Select all  Expand view

SetDlgGradient( { { 0.6, CLR_BLUE, CLR_WHITE }, { 0.4, CLR_WHITE, CLR_BLUE }, .F. } )

If the last element of the gradient array is .F., instead of an array, the gradient is horizontal.

   aGrad := { { 0.4, CLR_GREEN,  CLR_HGREEN }, ;
              { 0.6, CLR_HGREEN, CLR_GREEN  } }

   DEFINE BRUSH oBrush GRADIENT aGrad STYLE HORIZONTAL // or VERTICAL
   DEFINE BRUSH oBrush1 COLOR nRGB( 250, 213, 174 ) STYLE HORIZONTAL

   ACTIVATE DIALOG oDlg CENTERED

   RELEASE BRUSH oBrush

RETURN NIL

// FIN / END

I have put several of my gradients into functions .. very easy to use ...

Please ensure that the sum of the first column of all sub-arrays is 1.0.
Otherwise, your examples mislead other users who are new.

[Rick Lipkin]

Rao

I am a bit perplexed ? ... These functions work just fine for me ... what have I done wrong or need to change ?

Thanks
Rick Lipkin

ps, I have noticed with newer versions of FWH that the above gradients paint slower than in previous versions of FWH

[karinha]

Good morning Rick, can you make a complete example showing how your functions work?
